cariSpray oral spray bottle with features highlighted on a white background

CariSpray scientifically-backed formula contains:

  • Nano-Hydroxyapatite: The same mineral that makes up 97% of your tooth enamel. It remineralizes and strengthens teeth at the molecular level, using particles identical in size to those in natural teeth and bones—and in a concentration precisely matched to replace your teeth’s daily mineral loss.
  • Xylitol (25%): Clinically shown to support a balanced oral microbiome and help maintain a healthy mouth environment.
  • pH+ Buffering System: Sodium Bicarbonate and Potassium compounds that instantly balance mouth acidity.

Clinically proven, patent-pending technology with nano-hydroxyapatite remineralization helps protect against cavities before they start.

Found It Easy to Use

  • 1. pH Homeostasis Restoration

    The formulation quickly rebalances oral pH from acidic levels (≤5.5) to a more protective, alkaline state (≥7.0), creating the ideal environment for strong, healthy-looking enamel.

  • 2.Targeted Oral Balance

    Bacteria interact with xylitol thinking it’s sugar, but they cannot process it. This metabolic interaction supports a balanced oral environment, helping the mouth feel cleaner and fresher.

  • 3. Biomimetic Remineralization


    Precision-sized nano-hydroxyapatite crystals (20–80 nanometers) bond to the tooth surface, helping smooth, strengthen, and enhance the appearance of enamel by supporting its natural mineral balance.

    Pharmaceutical-Grade Clinical Validation & Purity Certification

    CARISPRAY Adults has undergone rigorous validation through accredited European laboratories following pharmaceutical manufacturing protocols. The formulation received comprehensive analytical verification through ISO-certified testing facilities, establishing clinical-grade purity and biocompatibility standards.

     

    Advanced Clinical Validation Protocol:

    • Sterile Microbiological Validation
    • Antimicrobial Preservation Efficacy
    • Dermatological Biocompatibility
    • European Pharmaceutical Compliance

    All procedures conducted under cGMP conditions by accredited laboratories, including Meyer d.o.o., Dr Koziej Clinical Research Institute, and Croatian National Institute of Public Health.

    • Finally broke my cavity cycle after 30 years

      I’ve battled cavities for years despite perfect brushing. My dentist blamed low pH, so I tried this spray—6 weeks later, my pH normalized and for the first time in decades, I heard “no cavities”!

      Sarah K., Verified Purchase

    • Avoided my worst fear — more dental work

      I’ve had dental anxiety since a painful root canal, but using this daily gave me control again. My last visit was just a cleaning—no drilling, no bad news. For once, I’m not dreading the dentist!

    • A product backed by real science

      Getting my autistic son to cooperate with tooth brushing was impossible. This spray is so gentle and tastes good enough that he actually opens his mouth for it.

      CariSpray comparison showing superior cavity protection

      US VS. THEM COMPARISON

      Not another harsh mouthwash or temporary fix. Just dentist-developed pH science that actually protect against cavities.

      Hey, I'm Dr. Toni – a dentist, founder of OralAdvance Labs and creator of CariSpray

      The moment that changed everything happened during a routine checkup. A 6-year-old named Luna needed her third filling in just one year. As I prepped the drill, her mom's voice cracked: "Doctor, I don't understand. We brush morning and night with fluoride toothpaste. We cut back on snacks and juice. I even bought those expensive kids' vitamins. What else can I possibly do?"

      FAQ

      CariSpray is the world’s first nano-hydroxyapatite oral spray, creating an entirely new category of oral care. It works through a triple mechanism: restoring pH balance, promoting microbiome optimization via xylitol, and enabling molecular-level tooth remineralization.

      Yes. CariSpray is completely safe to swallow.

      The enamel on your teeth is composed of approximately 97% hydroxyapatite, and CariSpray’s 0.45% nano-hydroxyapatite concentration is carefully designed to replace the minerals your teeth naturally lose each day from dietary acids.

      Since these are biocompatible minerals already found in your body, swallowing the product poses no risk. No rinsing is necessary.

      OralAdvance partners with FLUIDINOVA,
      Europe’s leading manufacturer of high purity, research-grade nano hydroxyapatite.

      Key material specifications: Sub-100 nm rod-shaped particles 98% dentin tubule occlusion (vs. 82% for competitors) RDA <10 (extremely low abrasivity).

      Pharmaceutical-grade purity.

      We use the only nano-hydroxyapatite approved by the EU's Scientific Committee on Consumer Safety as entirely safe, biocompatible, and non-toxic.

      Yes – both clinical and laboratory studies confirm its effectiveness.

      30-Day Use Study Results:

      ✓ 84% less staining

      ✓ 73% less tartar buildup

      ✓ 82% of users said their teeth looked whiter and brighter

      ✓ 100% found it easy to use

      Laboratory Findings:

      • 62% improved cavity protection within just 3 minutes

      FLUIDINOVA Independent n-HA Research:

      • Complete dentin tubule sealing within 7 days

      • Sustained remineralization even after acid exposure

      • Electron microscopy confirms nano-hydroxyapatite particle integration into
      the enamel microstructure

      Research shows that up to 10–14% of enamel hydroxyapatite can be lost during cavity development in typical caries models lasting 15–30 days. This translates to an average daily mineral loss of approximately 0.67–0.93%.

      The 0.46% n-HA concentration in CariSpray is precisely formulated to replace this daily loss and maintain optimal mineral balance.

      Results occur at multiple levels: Immediate: Fresh breath and cleaner mouthfeel.

      Within days: Improved oral pH balance

      After 2–4 weeks: Noticeable enamel smoothness and reduced sensitivity

      Long-term: Sustained remineralization and caries protection

      Clinical data show measurable results
      within days: Immediate: Fresh breath and cleaner mouth sensation

      1 week: 35% reduction in tooth sensitivity

      2–4 weeks: Up to 80% reduction in sensitivity

      6 months: Up to 62% reduction in long-term hypersensitivity

      As validated in FLUIDINOVA’s independent
      research.
